    ath79: add support for Senao Engenius EAP350 v1
    
    FCC ID: U2M-EAP350
    
    Engenius EAP350 is a wireless access point with 1 gigabit PoE ethernet port,
    2.4 GHz wireless, external ethernet switch, and 2 internal antennas.
    
    Specification:
    
      - AR7242 SOC
      - AR9283 WLAN                 (2.4 GHz, 2x2, PCIe on-board)
      - AR8035-A switch             (GbE with 802.3af PoE)
      - 40 MHz reference clock
      - 8 MB FLASH                  MX25L6406E
      - 32 MB RAM                   EM6AA160TSA-5G
      - UART at J2                  (populated)
      - 3 LEDs, 1 button            (power, eth, 2.4 GHz) (reset)
      - 2 internal antennas
    
    MAC addresses:
    
      MAC address is labeled as "MAC"
      Only 1 address on label and in flash
      The OEM software reports these MACs for the ifconfig
    
      eth0  MAC     *:0c    art 0x0
      phy0  ---     *:0d    ---
    
    Installation:
    
      2 ways to flash factory.bin from OEM:
    
      - if you get Failsafe Mode from failed flash:
          only use it to flash Original firmware from Engenius
          or risk kernel loop or halt which requires serial cable
    
      Method 1: Firmware upgrade page:
    
        OEM webpage at 192.168.10.1
        username and password "admin"
        Navigate to "Upgrade Firmware" page from left pane
        Click Browse and select the factory.bin image
        Upload and verify checksum
        Click Continue to confirm and wait 3 minutes
    
      Method 2: Serial to load Failsafe webpage:
    
        After connecting to serial console and rebooting...
        Interrupt uboot with any key pressed rapidly
        execute `run failsafe_boot` OR `bootm 0x9f670000`
        wait a minute
        connect to ethernet and navigate to
        "192.168.1.1/index.htm"
        Select the factory.bin image and upload
        wait about 3 minutes
    
    Return to OEM:
    
      If you have a serial cable, see Serial Failsafe instructions
      otherwise, uboot-env can be used to make uboot load the failsafe image
    
      *DISCLAIMER*
      The Failsafe image is unique to Engenius boards.
      If the failsafe image is missing or damaged this will not work
      DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
    
      ssh into openwrt and run
      `fw_setenv rootfs_checksum 0`
      reboot, wait 3 minutes
      connect to ethernet and navigate to 192.168.1.1/index.htm
      select OEM firmware image from Engenius and click upgrade
    
    Format of OEM firmware image:
    
      The OEM software of EAP350 is a heavily modified version
      of Openwrt Kamikaze. One of the many modifications
      is to the sysupgrade program. Image verification is performed
      simply by the successful ungzip and untar of the supplied file
      and name check and header verification of the resulting contents.
      To form a factory.bin that is accepted by OEM Openwrt build,
      the kernel and rootfs must have specific names...
    
        openwrt-senao-eap350-uImage-lzma.bin
        openwrt-senao-eap350-root.squashfs
    
      and begin with the respective headers (uImage, squashfs).
      Then the files must be tarballed and gzipped.
      The resulting binary is actually a tar.gz file in disguise.
      This can be verified by using binwalk on the OEM firmware images,
      ungzipping then untaring.
    
      The OEM upgrade script is at /etc/fwupgrade.sh
    
      Later models in the EAP series likely have a different platform
      and the upgrade and image verification process differs.
    
      OKLI kernel loader is required because the OEM software
      expects the kernel to be no greater than 1024k
      and the factory.bin upgrade procedure would
      overwrite part of the kernel when writing rootfs.
    
    Note on PLL-data cells:
    
      The default PLL register values will not work
      because of the external AR8035-A switch between
      the SOC and the ethernet PHY chips.
    
      For AR724x series, the PLL register for GMAC0
      can be seen in the DTSI as 0x2c.
      Therefore the PLL register can be read from uboot
      for each link speed after attempting tftpboot
      or another network action using that link speed
      with `md 0x1805002c 1`.
    
      uboot did not have a good value for 1 GBps
      so it was taken from other similar DTS file.
    
    Tested from master, all link speeds functional
